“I haven't been drinking, since January I just put down the alcohol, I was going to detox," he told Harry Connick Jr. on his talk show.

"I had heard—I don’t know how true it is—but I heard you can regenerate your liver in six months," he said. "I was like let me see if I can go six months, and I just haven’t gone back."

Cutting out drinking can, in fact, have a quick and dramatic effect on your liver—and your overall health. A small-scale study in 2015 found that when regular drinkers stopped consuming alcohol for just one month, indications of damage and scarring in their livers went down by 12.5 percent. They also saw improvements in their blood pressure, cholesterol, and diabetes risk.

Studies have shown that all the empty calories you consume from alcohol can cause you to gain weight over time, so it’s only natural that Robinson started to drop pounds. He was also able to slim down by adopting a vegan diet, as well as incorporating more movement into his daily routine.

“Then working out and I’ve been trying this vegan lifestyle, too...it’s amazing," Robinson said. "There are so many great vegan restaurant and dishes.”
